System and method for providing location information to a public safety answering point during an emergency 911 call from a softphone
First Claim
1. A system for providing location information to a public-safety answering point during an emergency 911 call from a softphone, said system comprising:
- a network access point configured to receive calls from softphones;
a soft-switch in communication with said network access point, said network access point configured to communicate a call from a softphone to said soft-switch;
a database configured to store network address information of selective routers on a network through which information is communicated to public safety answering points operating to service emergency 911 calls; and
a gateway in communication with said network access point, soft-switch, and database, and, in response to receiving an emergency 911 call from the softphone via said softswitch, request selective router information, from said database, of a selective router through which information is to be sent to a public safety answering point servicing an area including said network access point, wherein during the emergency 911 call, the softphone, in response to receiving an indication that an emergency 911 call is connected with a public safety answering point, being configured to communicate address location information of the softphone to the public safety answering point in a caller ID data packet by replacing a name field of the caller ID data packet with the address location information while maintaining date, time and telephone number information of the caller ID packet.

Abstract
A system and method for providing location information to a public safety answering point from a softphone may include receiving, at a network access point, an emergency 911 call from the softphone. The emergency 911 call may be communicated to a public safety answering point. In response to a call connection message being received, an address location of the network access point to which the softphone is in communication in placing the emergency 911 call to the public safety answering point may be communicated in a type II caller ID data packet. The softphone may generate the type II caller ID data packet with the address location in a data field, such as a data field typically used for name information of a caller.

14. A computing device executing software of a softphone, the computing device comprising:
-
a telephone module configured to enable a user to place emergency 911 telephone calls; an address location update module configured to;
determine that location of the softphone has changed;
request a current address location from a user of the softphone;
update the current address location; and
store the updated current address location;said telephone module further configured to; cause the computing device to initiate and complete a connection with a public safety answering point; look-up the current address location in response to receiving notification that an emergency 911 call is connected with a public safety answering point; generate a caller ID data packet with the current address location contained therein by replacing a name field of the caller ID data packet with the address location information while maintaining date, time and telephone number information of the caller ID packet; and cause the computing device to communicate the current address location to the public safety answering point in a caller ID data packet. - View Dependent Claims (15)
